The paper describes the passive magnetic attitude control system developed
for the Swedish nanosatellite MUNIN, its composition, and the results of th
e mathematical modeling of the satellite motion around its center of mass u
nder the effects of external torques and control by this attitude control s
ystem. The satellite MUNIN is to be oriented along the local vector of inte
nsity of the geomagnetic field. The problems, which are expediently conside
red hereafter are formulated too. (C) 2000 Elsevier Science Ltd. All rights
